Answer» 1. Fossils are evidence of ancient life forms or ancient habitats which have been preserved by natural processes. 2. Fossil evidence is typically preserved within sediments deposited beneath water and land. 3. They can be actual remains of once lived such as bones or seeds or even traces of past event such as dinosaurs foot print or ripple marks on a pre-historic shore. 4. Usually when organisms die, their bodies will be decomposed and lost. 5. But sometimes the body or at least some parts may be in an environment that does not let it decompose completely. 6. For example if a dead insect get caught in mud, it will not decompose quickly and the mud will eventually harden and retain the impression of the body parts of insect. 7.
